Patent GB-190817311-A (GB)
Title: Improvements in and relating to Dynamo Electric Machines.
Inventor: FERGUSON THOMAS
Filed: 1908-08-18
Granted: 1909-04-29
Abstract: 17,311. Ferguson, T. Aug. 18. Dynamos, regulating; brushes and collectors and holders therefor.-Consists in an improved method of regulating the output of dynamos by moving the armature axially with regard to the field by means of the driving-force of the belt, and is specially applicable to machines driven at a varying speed, such as train-lighting or ventilating machines. The sleeve g, Fig. 1, to which the armature is rigidly attached is loose on the shaft a, and is normally held against a shoulder a<1> on the shaft by a spring n and sliding collar l. The sleeve carries a thrust-block o having a camsurface which bears on a pin p or roller rigidly mounted on the shaft. The shape of the cam and the compression of the spring are adjusted in relation the pull of the driving-belt and the electro-magnetic pull between the armature and fields so as to allow the armature to slide out of the field to give the required output characteristic as the speed varies. The pin p may project on both sides of the shaft, the cam in this case being double to bear on both ends of the pin. The normal output of the machine may be varied by causing the pin to bear on either of two concentric cam surfaces of different radii ; or, as shown in Fig. 9, by providing the cam with a wide sloping face p and locking the pin in the shaft a at any required radius. The compression of the spring n may be altered by nuts on the collars l, m, or by means of an axial set-screw in the end of the shaft bearing on a sliding block which presses against the collar m. The spring n may be replaced by the linkage s and cross-spring t shown in Fig. 10, the normal output being controlled by tightening the spring by means of an adjustable straining-hook or by using springs of different strengths. In machines subject to sudden changes of speed, the effect of armature inertia may be reduced by forming a dash-pot on the collars l, m. In an alternative form, the pin p is attached to the sleeve and the cam is formed on the shaft a ; or the armature and cam may be rigidly mounted on the shaft while the pin is carried by a sleeve attached to the pulley d, the shift being free to slide in its bearings. To enable the brushes to rock automatically with variations of load, they are carried by a plate j, as shown in Fig. 3, which is a sectional view on the line x-x, Fig. 1. The plate is loose on the sleeve g, and has projections j<1>,j<2>, one of which abuts on a fixed plate v according to the direction of rotation. The plate is tapered, as shown in Fig. 1<a>, so that the lead of the brushes depends on the axial position of the armature.

Motor road vehicles.-Relates to variable-speed gearing of the kind described in Specification No. 15,322, A.D. 1908, applicable to motor-vehicles, and comprising sun-and-planet gearing arranged within a dynamo-electric brake or retarding-device. The multipolar field-magnet 1, Fig. 1, is stationary, and the armature 2 is loosely mounted upon the engine and driven shafts 3, 4, which are co-axial and carry spur-wheels 9, 10 forming the sunwheels of the sun-and-planet gearing. The planetwheels 7, 8 are secured to a shaft 6 loosely mounted in the end plates 5 of the armature 2. Several shafts 6 and planet-wheels are employed in practice. The armature 2 may have short-circuited windings like the rotor of an induction motor, or it may be simply a mass of magnetic material. At starting, the engine shaft 3 rotates the planet-wheels 7, 8. and the armature 2, idly around the sun-wheels 9, 10. When the field-magnet 1 is energized, the armature 2 is retarded or braked, causing the sun- and-planet wheels to drive the shaft 4. In a modification, two mechanically-coupled armatures, each having its own field-magnet structure, are employed.

Title: Improved Automatic Switch Gear for the Remote Control of Electric Motors.
Inventor: MEDWAY MATTHEW THOMAS
IPC: H02P7/00
Filed: 1909-08-13
Granted: 1910-08-15
Abstract: 18,675. Medway, M. T., and Scott. M. D. Aug. 13. Systems for continouscurrent motors only electric braking.-A switch in the armature circuit of a motor is opened by the braking-current when the motor runs as a generator and so prevents reversal until the motor comes to rest. The switching.system is shown applied to the circuits of a lift motor. When the controller is moved to its first position, the arm c is in contact with the contact c<1>. Current then flows from the main a, through the switch e, the contact c<1>, the brake coil f and the fuse g to the main b, thus lifting the brake. In the next position, the arm c touches the contact c<2> and current is thereby supplied to the left-hand half of the solenoid h. This solenoid operates a reversing-switch which has four sliding arms k, l. m, n; and the core moves so that the bar m engages contacts m<2>, m<3> and the bar n engages contacts n<1>, n<2>, while the circuit at k is broken. The movement of the reversing-switch closes the circuit of the coil p, which actutes six switches j, o, q, r, s, t. The operation of the switches o, t maintains the circuit of the coil p through the resistance o<1> and the contacts t. Another circuit is closed through the solenoid u which opens the switch e, the circuits closed by this switch being maintained by the switch t. The circuits of the field and armature of the motor v are closed when the coil p operates the switches q, r, and the coil u raises its core to cut out resistance w. When the controller c is brought back to its central position, as shown, the coil p is deenergized and the switches j, o, q, &c. revert to their original positions, thereby cutting off the motor from the supply. The motor then runs as a generator, and the current from the armature passes through the coil u and holds up the switch e. Current is therefore cut off from the controller c until the motor comes to rest and the switch e closes. The controller c may then be reversed, and the right-hand half of the solenoid h energized. The reversing.switch then operates to reverse the armature current. To stop the motor quickly, the armature mav be short-circuited through a resistance x, less than the resistance of the coil u.

Title: An Improved Apparatus for Separating Measured Quantities of Grain from Bulk and Delivering same.
Inventor: COSFORD ALEXANDER
IPC: B65G65/48
Filed: 1909-09-27
Granted: 1910-06-23
Abstract: 21,983. Cosford, A. Sept. 27. Fixed - chamber apparatus for granular materials. - Grain is delivered by a conveyer 28, Fig. 4, into a receptacle 22, and when this is filled, a gate 12 automatically shuts off the supply of grain and a sliding bottom 21 is operated to allow the grain to pass out of the receptacle. The gate is pivoted to a lever 13, Fig. 1, which is pivoted at its other end to the conveyer casing, and is automatically closed by a spring 14 but is raised by the action of a pin 15 on a gear wheel 16, arranged to be put in mesh with a gear wheel 32 on the conveyer shaft 29. Some of the teeth on the driven-wheel 16 are cut away so that it cannot receive a continuous rotation from the driving-wheel 32. The wheel 16 is mounted on a shaft which projects through the conveyer casing and carries at its opposite end, as shown in Fig. 5, a crank 18 which engages a slotted lever 19 pivoted on the shaft 25, the lower end of the lever being connected to the bottom 21, which slides in guides 24, and, on the other side of the conveyer casing, the shaft 25 carries an arm 26, which is also connected to the sliding bottom 21. In the receptacle 22, a float or controller 36, Fig. 4, is mounted loosely on the central rotating shaft 38, of square section, so that as the receptacle fills the float rises. The shaft is driven through bevel-gearing 39 from a toothed wheel 42 driven from a toothed wheel on the shaft 29 of the conveyer. When the receptacle is filled, the float strikes a lever 34, which then engages a pin 35 on the wheel 16 so as to put the wheels 32, 16 into mesh with each other, and as the wheel 16 rotates, the pin 15 moves out of engagement with the lever 13, allowing the gate 12 to close. At the same time, by means of the crank 18 and levers 19, 26, the sliding bottom 21 is opened for discharge.

Granted: 1910-09-08
Abstract: 25,700. Lockwood, J. Nov. 8. Smoke, consuming; grates; fire-covers.-The combustion products from the fire-place of a kitchen range or parlour grate are led downwards into a chamber which is formed in the space behind, beneath, and adjacent to the grate, and are there mixed so that the smoke is consumed before passing into the flues. Fig. 1 shows a convertible open-and-close kitchen range with such a chamber A comprising the space between the ovens C and behind the ash-pit and the grate B. The combustion products enter the chamber A principally through a wedgeshaped flue G, those descending from near the fire-cover H being rendered smokeless by the hot gases issuing from the perforations b<2> in the fire-back b<3>. Another part of the combustion products passes through channels formed by ribs h<1> on the underside of the fire-cover H, and thence through a flue c<3> to the chamber A. When the fire-cover H is drawn forwards over the fire, a flange on its rear end closes the entrance to the hood D; if the damper K<1> is then shut, all the combustion products descend to the chamber A. In a modification, the boiler E and hood D are omitted; the upper side of the boiler is replaced by a perforated plate, and the forward side of the boiler by an inclined imperforate slab forming with the fire-back b<3> a tapering chamber G like that shown in Fig. 1. The front surface of the ash-pit, in this modification, is inclined downwards from the rear edge of the grate bottom b<1> to the lower part of the range front, so as to enlarge the space A. The invention is shown in Fig. 7 as applied to an open fire-place. In this case the combustion products pass through the tapering chamber G to a chamber A enlarged by forming a depression Y in the hearth. A similar depression may be formed in the setting of ranges &c.
